Within the history of modern philosophy, the philosopher and theologian Søren Aabye Kierkegaard (1813-1855) is seen as a harsh critic of the philosophy of Georg Wilhelm Friedrich Hegel (1770-1831). The purpose of this study is to highlight the theological (especially dogmatic and moral) dilemmas that Kierkegaard attributes to the Hegelian philosophical system. For Kierkegaard, the attempt to elucidate the mystery of Christian teaching by means of autonomous human reason is to falsify it. Kierkegaards criticism of Hegelianism intensifies because the Hegelian System enters Protestant theology like a Trojan horse, through the representatives of the Danish Church, theologians and clerics. Thus, a form of Hegelian Christianity is born. For Kierkegaard, this means a falsification of authentic Christian teaching, a departure from the simplicity of original Christianity. The entire criticism brought by Kierkegaard to Hegel can be summarized in two main points: (1) the interpretation of the category of faith, (2) and the relationship between the finite and the infinite or the difference between man and God.
